Our valves feature flange connections that comply with ASME B16.1 /ASME B16.47, AWWA C207, EN1092/BS4504 standards. This ensures compatibility with a wide range of piping systems and facilitates easy installation.
Inspection and Testing:
Our valves undergo rigorous inspection and testing procedures in accordance with EN12266-1/API 598/ISO5208 standards. These tests guarantee the valves’ structural integrity, leak-tightness, and overall performance.
Top Flange:
Our valves are equipped with top flanges that adhere to ISO5211 standards, ensuring proper sealing and secure valve operation.
Benefits of Eccentric Flanged Butterfly Valves:
Our double eccentric flanged butterfly valves offer numerous advantages over other types of butterfly valves:
1. Superior Sealing Performance: The offset disc design provides a tight seal, minimizing leakage and ensuring reliable flow control even under high-pressure conditions.
2. Reduced Wear and Tear: The minimal contact between the disc and the seat significantly reduces wear and tear, extending the valve’s lifespan and reducing maintenance requirements.
3. Longer Service Life: Due to their reduced wear and tear, eccentric flanged butterfly valves have a longer service life compared to other butterfly valve types.
4. Easy Operation: The double eccentric design allows for smooth and effortless operation, even under high-pressure conditions.
5. Wide Range of Applications: Eccentric flanged butterfly valves are suitable for a diverse range of industries, including water treatment, chemische Verarbeitung, power generation, and oil and gas.
Comparing Mono Flange Butterfly Valves with Eccentric Flanged Butterfly Valves:
Mono flange butterfly valves, which have only one flange, are often compared to double eccentric flanged butterfly valves. While mono flange butterfly valves are more compact and lightweight, they have certain limitations:
1. Sealing Performance: Mono flange butterfly valves have a less effective seal compared to double eccentric flanged butterfly valves, making them less suitable for high-pressure applications.
2. Wear and Tear: The single flange design can lead to increased wear and tear, resulting in a shorter lifespan and higher maintenance requirements.
3. Anwendungseignung: Mono flange butterfly valves are primarily used in low-pressure applications, such as water distribution systems, while double eccentric flanged butterfly valves are more versatile and can be used in a wider range of industries.
Applications of Eccentric Flanged Butterfly Valves:
Eccentric flanged butterfly valves find application in various industries, einschließlich:
1. Wasserversorgung: These valves are used to control the flow of water in water treatment plants and distribution systems.
2. Chemische Verarbeitung: They are suitable for handling corrosive chemicals and liquids in chemical processing plants.
3. Energieerzeugung: Eccentric flanged butterfly valves are used in power plants to regulate the flow of steam, water, and other fluids.
4. Öl und Gas: These valves are employed in oil and gas industries for controlling the flow of hydrocarbons and other fluids.
5. Mining: They are used in mining operations to regulate the flow of slurries and other abrasive materials.
